Steps to reproduce

I'm on Linux Mint 20.3 Cinnamon and using Ferdium.

1. Open Ferdium, go to Messenger and open a conversation with someone.
2. Click "Attach a file" and choose an image file (e.g PNG image) from disk (OR drag-and-drop that file OR ctrl+c-ctrl-v an image).
3. It shows "Sending..." indefinietly in Ferdium. The image is not visible by me in other clients and by people to whom the image was sent.
4. Same problem exist when logged to Messenger in Chromium Browser. In Firefox everything is fine.

Expected Behavior

In few seconds the sent image shoud be visible by people to whom it was sent and by me in other clients.

Actual Behavior

The sent image is not visible to anyone outside Ferdium client where it is saying "Sending..." indefinitely.
